I might move to another state, and I have soo many pending, what do I do? Can i tell them to forward them or something? Or will that lucky person be recieving all my autographs?
I believe that when you move to a new home, all your mail that is being sent to the previous home will have a yellow sticker on it that should notify the postal service of your new address, and they'll ship it there. But just to be safe you should call the postal service and tell them that you changed your address, because after about a year, this does not work anymore and any mail that is sent to your old residence will stay there.
When someone moves, like RentRocks314 said, it is forwarded to your new address. Provided that you tell the post office to. This is called a forwarding order. They last a year.
